STANISLAW WISNIEWSKI, OF SOUTH LIANCHESTER. CONNECTIGUT.

BOAT-PROPELLING DEVICE.

Application filed May 12, 1922. Serial No. 560,331.

i To all whom it may concern Be it known that I, STANIsLAw Was- NIEWSKI, a citizen of Poland, residing at South Manchester, county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Boat-Propelling Devices, of which the following is is a specification.

This invention relates to improvements in boat propelling devices, particularly to devices operated by human power for driving two paddle wheels for propelling the boat through the water, as for instance described in my Patent No. 1,410,048 of March 21,1922.

The principal object of the invention is the provision of a device of this character adapted to be actuated by two persons sitting at the ends of a board supported in its middle or center of gravity to operate the board in the manner of a see-saw.

Another object of the invention is to provide a device in which the power developed by the operation of the see-saw is readily transformed and transmitted to the paddle,

wheels for propelling the boat.

A further object of the invention is to provide a boat propelling device which can be cheaply constructed and installed in any boat, and which is capable of entertaining persons, constituting a means for a healthy outdoor sport.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings forming a ma terial part of this disclosure, and in which Figure 1 is a top plan view along line 3-3 of Figure 2 showing a boat equipped with the preferred form of propelling device.

Figure 2 is a longitudinal vertical section on line 4=4l of Figure 1, and I Figure 3 is a cross-section on line 55 of Figure 1.

As illustrated in the drawings the boat is constructed in general in the same manner as described in my Patent No. 1,410,048, with the exception of the following differences:

To the inner ends of the horizontal operating rods 62 and 63, operating spring links 64 and 65 of a peculiar shape as best illustrated in Figure 1 are secured which are pivoted at one end as indicated at 66 and 66 to the ends of links 62 and 68 and at the other, as indicated at 67 and 67' to the boat, and which carry operating fingers 68 and 69 respectively for operating the horizontal ratchet wheel 70 in the same manner the fingers as and a l: operate wheel In order to allow a turning of the boat by the operation of the paddle wheels 71 and 7 2, the shaft 73 carrying these paddle wheels is divided, and its parts 74 and 7 5 can be connected with the central part 73 by means of clutches 76 and 77 adapted to be operated by means of operating rods 78 and ban dles 79.

Thus, if it is desired to make a turn to the left, the left hand. wheel is disengaged while the right hand wheel is operated. In order to permit a change in the direction of travel, the shafts 80, 81 carrying the gears 82, 83 which are in engagement with gears Set, 85 on the wheel shafts and carry at their inner ends the bevel gears 86, 87 adapted to be operated by the bevel wheel 88 operated from shaft 89 of ratchet wheel-70, are divided and provided with clutches 90 and 91 adapted to be operated by rods 92 with handles 93.

It will be obvious that a device of this character may be made in many sizes and that changes may be made in the general arrangement thereof as well as in the construction of its minor details without departing from the scope and spirit of the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is- 1. In a boat propelling device of the character described, a pair of propellers, a driv-- ing mechanism, comprising a pair of vertical bevel gears, a horizontal bevel gear in mesh with said vertical bevel gear, means for coupling said horizontal bevel gear with said driving mechanism, a divided shaft for said propellers, a divided shaft for each of said vertical bevel gears, gears on the parts of said propeller shaft, and gears on the parts of said bevel gears in mesh with said gears in the propeller shaft, couplings for coupling the parts of said shafts and operating means for said couplings.

2. In a boat propelling device of the char acter described, a see-saw, a pair of spring controlled horizontal rods, operating connections between said rods and said see-saw for transforming the see-saw movement into shafts for said vertical bevel gears, clutches for couplin the partsof said shaft, eans for operating said clutches and gears on said shafts in mesh with said gears of said propeller shaft, for allowing a steering of the boat by the operation of said clutches and for reversing the direction of propulsion.

In testimony whereof I have aifixed my signature.
